The popular SPHERIC SPH Training Day will take place on Monday 25 June, the day before the Workshop, from 0930 to 1600. Following tradition, the day will combine lectures with hands-on practice on SPH software. The fee for the day is €40, including lunch. The day is ideal for students and researchers who are beginning to explore SPH, and anyone who is curious about the method. It will also be of interest to more experienced SPH researchers and users who have an interest in the specific topics of the day, and those who wish to advance their software skills. For all participants, the day provides time and space to consider and discuss fundamental topics in depth.
The SPHERIC Training Day is approved by Engineers Ireland as Continuing Professional Development (CPD).
Registration is essential. (You can attend the Training Day without attending the full Workshop.)
Please see the programme for full details of timing and venues.
Lecture, 0930-1100, room G047
Fundamentals of SPH
Dr. Matteo Antuono, CNR-INSEAN, Italy
This lecture will offer attendees an understanding of the underlying concepts of SPH and its fundamental differences from classical computational methods. While covering the foundations comprehensively, Dr. Antuono will also present some of the most recent ideas. Topics include:
- Introduction to SPH (historical notes)
- Basic concepts (interpolation and smoothed operators)
- Duality between continuum and discrete formalisms
- SPH in fluid dynamics: the weakly compressible and incompressible approaches
- Weakly compressible SPH and its conservation properties (mass, momentum, energy)
- Boundary conditions along the free surface and along solid boundaries (mirroring techniques, surface forces etc.)
Matteo Antuono graduated in Applied Mathematics in 2004 at the University of Rome “La Sapienza”, and then in 2008 obtained a PhD in Fluid Dynamics at the University of Genoa. He is currently a researcher at CNR-INSEAN, the Marine Technology Research Institute of the Italian National Research Council, where he is one of the team that develops delta-SPH. His scientific interests deal with both theoretical and numerical aspects of particle methods, gravity wave propagation and sloshing motions.

Delta-SPH: Theory and Applications
Dr. Salvatore Marrone, CNR-INSEAN, Italy
The application of the SPH method in the industrial context is rapidly increasing. The use of this method ranges from marine hydrodynamics to multiphase flows and fracture dynamics. This is possible thanks to the enlarging computational resources but, more importantly, to new models and enhancements that have been developed in recent years. The talk will focus on one of the most popular SPH variants, δ-SPH, highlighting the main advantages with respect to standard SPH formulations and providing some practical examples.
Salvatore Marrone is a researcher since 2014 at CNR-INSEAN, the Marine Technology Research Institute of the Italian National Research Council. In 2012 he obtained his PhD degree in Theoretical and Applied Mechanics at the University of Rome “La Sapienza”. He was a Post-doctoral fellow at Ecole Centrale de Nantes in 2013 where he worked on the application of SPH solvers for the design of wave energy converters under extreme conditions. The main focus of his research is the computational aspects of mesh-free numerical methods (SPH and Diffused Vortex Hydrodynamics) and their applications in naval and marine engineering contexts. He is one of the developers of delta-SPH.
Practical Session, 1400-1600, CA112
Simulation and Postprocessing
The DualSPHysics development team
The afternoon will be devoted to hands-on practice in setup and execution of SPH models, and visualization of output data. Topics will be demonstrated through practical examples in the open-source SPH solver DualSPHysics. This session will be led by the best possible tutors, the DualSPHysics developers themselves. They will be available throughout the session to support participants one-on-one and share their knowledge. Desktop PCs will be provided, with all necessary software.
Dr Alex J.C. Crespo is a Senior Researcher at The University of Vigo, Ourense in Spain. As an expert on Smoothed Particle Hydrodynamics, he obtained his PhD in 2008 developing and using SPHysics for free-surface flows. He has more than thirteen years of experience working on SPH collaborating closely with institutions in the UK, Italy, Portugal, Belgium and Spain. He is one of the core developers of the SPHysics and DualSPHysics. Nowadays he is pushing the application of SPH for real-life engineering problems such as numerical modelling for coastal protection from extreme and dangerous events and numerical design of wave energy converters. Since 2013 he has been a member of the Steering Committee of SPHERIC.
Dr. Benedict D. Rogers is a Reader in the School of Mechanical, Aerospace & Civil Engineering at the University of Manchester, UK. He is a founding member of SPHERIC, and has served as its Chair since 2015. He has worked on SPH for over 15 years. He is a core developer of the open-source SPH codes SPHysics, SWE-SPHysics and DualSPHysics. His research activities include numerical simulation and experimental investigation of free-surface flows, water waves and coastal hydrodynamics, shallow water equations (SWEs), natural hazards modelling (flooding and tsunamis). He specialises in the use of smoothed particle hydrodynamics (SPH) and finite volume methods (FVMs), accelerated using GPUs) and massively parallel systems. New applications of SPH are also being explored, such as high-temperature and multi-phase simulations including laser processing, intumescent paints, sludge flows, etc.
Dr José M. Domínguez Alonso is a Postdoctoral Researcher at The University of Vigo, Ourense in Spain. His research activity is mainly focused on computational fluid dynamics using HPC (High Performance Computing) and its application to coastal engineering. He obtained his PhD in 2014, where he focused on accelerating numerical models such as SPH using HPC. As an expert developer, he has been working during the last years using new novel technologies such as GPUs. He is one of the main developers of the DualSPHysics code.
